Parenchymal brain lesions associated with cerebral venous thrombosis

T2-weighted hyperintensies on brain MRI in acute CVT may be due to venous infarction and cerebral edema. The distribution of these findings in CVT commonly extends beyond typical vascular territories found in other cases of arterial ischemic stroke. Bilateral thalamic edema (A) is identified on an axial T2-weighted image in a case of deep cerebral venous system thrombosis. Left temporal venous infarction (B) is seen on a coronal T2-weighted image along with a thrombosis of left lateral sinus (arrow).
